Section 1: Introduction
This section provides information on the use of the Communication Interface with a control system or interrogating
computer. Appropriate software within the control system or on the interrogating computer (e.g. Reydisp
Evolution) is required to access the interface.
The relay data communication facility incorporates user selectable protocols to provide compatibility with control
and automation systems.
This section specifies connection details and lists the events, commands and measurands available in the
IEC60870-5-103, Modbus RTU, DNP3.0 and optional IEC61850 protocols.
When IEC60870-5-103 protocol is selected the relay can communicate with PCs running Reydisp software which
provides operational information, post-fault analysis, settings interrogation and editing facilities etc. Reydisp
software can be downloaded from our website
